To all whom it may concern.-

Be it known that I, FREDERICK A. THUM, a citizen of the German Empire,residing at Newark, in the county of Essex and State of New Jersey, haveinvented certain new and useful Improvements in Tilting Anode-Molds, ofwhich the following is a specification.

My invention has reference to improvements in tilting molds for castingmetallic anodes and in particular to means for facilitating the removalof the cast anodes from the molds.

. For this purpose my invention consists, essentially, in hinging to thebody of the mold that part of the rim which forms the end face of theupper or suspension end of the anode in such a manner that whenv thispart of the rim is turned away from the bottom of the mold the anode isfree to slide outwhen the mold is tilted.

Anodes with horns or arms cast thereon for the double purpose ofsuspension and of making electric contact are almost universally used inrefining metals by electrolysis. These horns or arms, being supportedupon electric conductors above the level of the electrolytes within thetanks, are not dissolved. They are a considerable addition to theresulting anodescrap of an electrolytic refinery, and it is thereforedesirable .to make them as light as possible. Some difficulties havebeen encountered in removing such anode-castings from the molds andvarious means have been tried for effecting the removal more rapidly andwith the least amount of labor and expense. I have overcome thedifficulties by the use of a tilting mold, which has the part of the rimforming the outer edge of the upper or horn end of the. anode separatelyhinged to the body of the mold, so that when this part of View of themold. Fig. 4 is an end View of the mold in Fig. Fig. 5 is a longitudinalsection, and Fig. 6 an elevation of a modification. Similar letters ofreference designate corresponding parts throughout the several views ofthe drawings.

Referring now to Figs. 1, 2, 8, and 4, the letter A designates the bodyof the mold, which consists of a plate with trunnions t and with araised rim a, cast thereon, following the j is a ring on the hinged rimB for turning it by, the protected hand or by means of a hook. The innerface I) of the hinged rim B is shown sloping, so that the anode thrownagainst it when the mold is tilted acts as a wedge and starts the rim Bon its hinges.

O is the bed-plate, anchored tothe foundation D by bolts f and providedwith bearings g for the trunnions t of the mold. The bedplate has anotch h, adapted to be engaged by a catch a, hinged to the mold, so asto hold the latter in a horizontal position for casting. The catch hasan upwardly-projecting arm for releasing it by means of a hook or othersuitable tool when the mold is to be tilted. Adjustable stops it on thesloped part of the bed-plate limit the motion of the mold when tiltedfor removing the anode-casting.

For casting anodes the mold is placed in a horizontal position and therim B turned down upon the mold, as shown in Fig. 1. is then poured intothe cavity of the mold. After the metal has set and shrinkage has takenplace the mold is tilted by releasing the catch 2', so as to assume theposition shown in Fig. 2, the throw being limited by the stops it.

The metal 1 The jar will start the castingE to slide out, as r is pickedup from the position shown in Fig. 2 by a suitable track, or it may beguided by ways upon a track or run into a cooling-tank.

The mold or a series of molds may be arranged in any of the well-knownways. They may be pivoted upon stationary bed-plates or upon movablebed-plates or turn-tables, the mold may be turned or tilted in any suitable manner, and the tilting of the mold, as well as the return to thehorizontal position, may be effected by hand or by automatic devices,and the method of hinging the rim B, so as to allow a clear passage forthe anode when turned out, may be varied'for instance, as indicated inFigs. 5 and 6, where the rim B is hinged above the body A of the mold bybolts 6 to eye-lugs c. The hinged arms of the rim B have holes 1. Oneach side of the mold are brackets m with notches. A bolt passes throughthe holes Z in the hinge-arms of the rim B and through the notches n ofthe brackets m, so as to hold the rim B away from the mold when the moldis tilted, as shown in Fig. in dotted lines, but allowing it to restfreely upon the bottom of the cavity when the mold is horizontal.

My invention is not restricted to the form of the anode shown. It may beapplied to any form which admits the cast anode to slip out of an openend without obstruction.

What I claim as new is- 1. In atilting anode-mold, the combination withthe body of the mold of a separate rimpiece hinged to an open end of themold, which hinged rim in its normal position for casting the anoderests upon the bottom of the mold-cavity and completes the rim, and

2. In atilting anode-mold, the combination with the body of the mold ofa separate rimpiece hinged to the horn end of the mold, which hinged rimin its normal position for casting rests upon the bottom of themo1dcavity and completes the rim, and when turned away on its hinges,leaves a clear space for the anode-casting to slide out on the bottom ofthe cavity, substantially as described.

3. In a tilting anode-mold, the combination with the body Aof the 'moldof a separate rim-piece B hinged to the body A beneath the plane of thebottom of the mold-cavity, and having its edge I) sloped to cause theanode to. act as a wedge in starting the rim-piece B on its hinges, saidrim-piece B in its normal position for casting resting upon the bottomof the cavity of the mold, and when turned away leaving a clear passagefor the anode-casting to slidev out on the bottom, substantially asdescribed.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
